    NHR-49/PPAR-α and HLH-30/TFEB cooperate for C. elegans host defense via a flavin-containing monooxygenase

    Khursheed A Wani et al.
    Genetic and molecular characterization showed that evolutionarily conserved flavin-containing monooxygenase (FMO-2) plays an important role in host defense in Caenorhabditis elegans, and its induction is dependent on conserved transcription factors, TFEB and PPAR-α.

    Somatic aging pathways regulate reproductive plasticity in Caenorhabditis elegans

    Maria C Ow et al.
    Somatic aging and germline RNAi pathways promote inheritance of ancestral starvation memory through reallocation of fat storage in Caenorhabditis elegans.

    Evolutionarily conserved long-chain Acyl-CoA synthetases regulate membrane composition and fluidity

    Mario Ruiz et al.
    Silencing the acyl-coA synthethase ACSL1 protects against saturated fat lipotoxicity by preventing the degradation of polyunsaturated fatty acids, allowing them to be incorporated into phospholipids and improves membrane fluidity.

    Re-visiting the trans insertion model for complexin clamping

    Shyam S Krishnakumar et al.
    Biochemical experiments provide support for the trans insertion model for clamping in the regulation of neurotransmitter release by complexin.

    Munc18-1-regulated stage-wise SNARE assembly underlying synaptic exocytosis

    Lu Ma et al.
    The Munc18-1 protein promotes formation of the t-SNARE complex and the half-zippered SNARE complex, two rate-limiting steps of SNARE assembly, to enhance membrane fusion.

    Non-canonical Hedgehog signaling regulates spinal cord and muscle regeneration in Xenopus laevis larvae

    Andrew M Hamilton et al.
    Unlike in early embryonic development, injured spinal cord and muscle in Xenopus laevis larvae recruit non-canonical Hedgehog signaling essential for their regeneration, while repressing Gli transcriptional activity.

    Metazoan evolution of glutamate receptors reveals unreported phylogenetic groups and divergent lineage-specific events

    David Ramos-Vicente et al.
    The animal phylogeny of glutamate receptors indicates that vertebrate types do not account for all receptor classes originated during evolution, neither are they the pinnacle of a linear evolutive process.

    Age-dependent deterioration of nuclear pore assembly in mitotic cells decreases transport dynamics

    Irina L Rempel et al.
    In replicative ageing yeast cells, an age-dependent impediment in proper assembly of nuclear pore complexes is associated with altered nuclear transport.

    Frontal eye field and caudate neurons make different contributions to reward-biased perceptual decisions

    Yunshu Fan et al.
    In monkeys making decisions that balance noisy evidence and reward expectation, frontal cortical and caudate activity reflect different computational components that are related to the monkeys' strategy.

    Dynamic effects of genetic variation on gene expression revealed following hypoxic stress in cardiomyocytes

    Michelle C Ward et al.
    Cellular stress in a disease-relevant cell type uncovers novel genetic effects on gene expression, which is likely relevant for disease.
